Study And Simulation Of Turbo Coding Technique In Lte Systems
Résumé: To examine the performance and the efficiency of turbo coding technique in the Physical layer (PHY) of the Long Term Evolution (LTE) standard, we implement MATLAB programs that gradually build and simulate the Transport Channel (TrCh) processing steps combined with modulation and scrambling based on predefined MATLAB functions that describe each involved processing step. The functions employ System Objects belonging to the Communication System Toolbox of MATLAB. The performance of each program is measured using graphs representing the BER as a function of Energy by bit (Eb/N0), by considering two different channel models: Additive White Gaussian Noise (AWGN) and Rayleigh. It is found that the performance over the AWGN channel model is better than the Rayleigh one, yet the later is considered practically to represent better the real system. Further, the performance depends mainly on a set of parameters: the modulation scheme, the number of decoding iterations, the Eb/N level, the coding rate and block size. Hence, a trade-off exists between the computational complexity and the performance of the system, and between energy efficient and bandwidth efficient code rates.
